Definitions

  • the invention relates to a wet room lamp according to the preamble of claim 1.
  • a wet room lamp of this type is formed with a two-part lighting overall housing, of which one part is a trough-shaped housing, the fastening elements for attachment to a support, for.
  • the other part is formed by an at least partially transparent cover, which is releasably connected by closure elements with the trough-shaped housing.
  • the cover In the overall housing formed by the trough-shaped housing and the cover at least one lamp is arranged, which is mechanically and electrically connected, and emits their radiated during operation light through the transparent cover for room lighting.
  • a wet room lamp of the type specified is z. B. in the EP 0 785 391 A1 described.
  • this prior art lamp are used to attach the cover on the trough-shaped housing in principle C-shaped closure elements, which are formed as separate components, and of which engages an end portion of the C-shape with a locking leg in a pocket-shaped undercut on the trough-shaped housing, over the Dividing joint between the trough-shaped housing and the cover extends beyond and engages with its other end portion of the C-shape edge of the cover with a certain tensile stress and thereby compresses the trough-shaped housing and the cover with a certain elastic clamping voltage.
  • the peripheral wall of the housing branches in the region of the circumferential housing edge with an outer and an inner edge region, which extend transversely to the plane of the housing opening and terminate at the housing edge.
  • the cover has a central edge region which extends in a comb-like manner at a lateral distance between the outer and the inner edge region, wherein the edge of the cover extends to the outer edge region and rests flat against the latter.
  • a luminaire is known with a first half-shell which forms a roof and a second, transparent half-shell which forms a trough.
  • the two half-shells have corresponding edges, which allow the assembly with an interposed elastic seal.
  • the object of the invention is to improve the protection against the ingress of water in the region of the dividing joint between the housing and the cover in the case of a damp-proof luminaire of the type specified at the outset. This object is solved by the features of claim 1. Advantageous developments of the invention are described in the appended subclaims.
  • the edge region of the cover with at least one peripheral edge on the Nutenwandung or the groove bottom.
  • the barrier effect against the ingress of water is improved by the investment of the edge of the central edge region on the outer and / or on the inner taper, because this system results in a circumferential barrier in the sense of a ring seal.
  • Another advantage is that the aforementioned system can form the stops by which the housing and the cover are spaced apart and abut each other in a certain position. Since such a stop extends circumferentially, the investment position is very stable. Special attacks between the housing and the cover can thus be omitted, which contributes to the simplification.
  • the embodiments of the invention are particularly suitable for a ceiling light in which the comb-like interlocking edge regions form a barrier against the ingress of water.
  • a ring clearance in the groove opposite the edge region of the cover. This space can serve to receive a ring seal, which allow a sealing of the dividing joint between the housing and the cover.
  • barrier web in a distance extending along the edge regions from the edge of the cover. This gives the outer edge region the shape of an effective drip edge.
  • trough-shaped housing 2 The main parts of in Fig. 1 in their entirety designated 1 wet room light are a trough-shaped housing 2, a so arranged by a plurality of circumferentially spaced closure devices 3 releasably connected cover 4 and a cavity 5 between the trough-shaped housing 2 and the cover 4 arranged lamp 6, which at least an unillustrated mechanical and electrical connection element is connected and held.

  • the closure member 3a extends from the end portion 3b substantially in an adapted to the associated outer shape of the housing 2 form the outside of the lamp housing to the cover 4, wherein it extends beyond the dividing joint 7 and with the associated end portion 3c a widening step 10 on the cover 4 engages behind, optionally engages in a recess 10a formed thereon.
  • the latter is done with an angular or curved inward extending, the end portion 3c forming Hintergreifschenkel 3d, which is secured by a securing device 14 in its tuck position.
  • the securing device 14 can be formed in that the Hintergreifschenkel 3d is biased obliquely inwardly against the widening shoulder 10 with respect to the transversely or perpendicular to the dividing joint 7 extending longitudinal center plane 15 of the lamp 1, so that this voltage him inward and not outward draws.
  • This is achieved in that the rear grip of the end portion 3c is arranged at a distance a from the longitudinal center plane 15, which is greater than the distance b of the rear grip of the end portion 3b of the longitudinal center plane 15.
  • Hintergreifschenkel 3d a clamping force 16 the effective direction includes an acute angle W1 with the longitudinal center plane 15.
  • This clamping force can be based on an elastic bending of the end region 3b and / or the end region 3c and / or the shape of the closure element 3a that follows the widening step 9 with respect to the step shape.
  • the closure element 3a is formed by a flat over its entire length extending web 3e, whose thickness is denoted by d.
